Violence

[HoreTore]

Heh nice try, it are outside factors that can bring it out, there is not a word on effectively subduing it

Edit, I am lying here, Frans de Waal latest does, but I haven't read it. It wasn't very well recieved so I didn't bother, AdrianII liked it

Marvin Harris also explains social phenomena as a result of ecology instead of biology, and his writing style is pretty fun as well, you should check it out

Back on topic, if outside factors can increase aggression/violence, then it stands to reason that a change in those factors can also serve to reduce it, doesn't it?

And if a set of factors can result in permanent war, then another set of factors which brings permanent peace must exist, right?
